摘要：
For the three-dimensional guidance problem of multiple missiles cooperatively intercepting a maneuvering target, a predefined-time cooperative guidance law with impact time constraint and line-of-sight angle constraint is proposed in this paper. The predefined-time cooperative guidance law has two projection components. Firstly, a new predefined-time multi-agent consensus protocol is proposed, and then the predefined-time cooperative guidance law command on line-of-sight direction is designed to guarantee all the missiles intercept the maneuvering target simultaneously. In addition, a new predefined-time non-singular fast terminal sliding mode surface is proposed. On this basis, the pre defined-time cooperative guidance law command on the normal line-of-sight direction is designed, which makes the missiles converge to the desired line-of-sight angle in a predefined time. Finally, the effectiveness of the proposed predefined-time cooperative guidance law is verified by three-dimensional numerical simulation. © 2023 China Spaceflight Society. All rights reserved.
